I have Salsa music which is too fast to teach people to dance to. Is there a software tool I can use to slow down the .mp3 or .wav files by about 10 t0 20%. There is no vocals so it does not matter if the music does not sound quite right. Any help would be greatly appreciated. Regards,
Most audio-editors softwares can do that. You can download shareware / trial version of Goldwave (=shareware) or SoundForge (=trial)to do that. There ougth to be some freeware tools too , but am too arsed to get heavy with google today (did do that yesterday too much..) Goldwave: http://www.goldwave.com/ Sound Forge: http://www.sonicfoundry.com/download/step1.asp?CatID=1 Terminology usually used on sound editors to do what you're up to is referred as: a) Pitch = slows/speeds up rate, also alters vocalist tone (you know, chip munk effect..), pitch is "standard" audio-editing terminology, others mentioned are actually "pitched" too, but tries to use different algoritms/filters, usually trying to keep vocalists tone same while backround music speed is altered. Can produce very poor results, so use with caution.. such kind of filtering is called as: B) Time Warp (GoldWave filter, -->effects--->Time Warp) C) Sound Forge uses similar kinds of filters, names escapes my memory for now. Edit: Just checked out, opened forge, and suprise suprise, technique is called as "Time Stretch, --->process-->Time Stretch Generally speaking, Forge is more advanced too you're not going to buy it, I'll bet on that.. Hope that helped you.
I believe that the WaveEditor that's normally packaged with Nero can slow down .WAV files. I know that the Sound Recorder program within Win98 can alter the pitch/speed of .WAV files.
If you want to use a free program then go for Sonique! It has an adjustable pitch and is easy to use. http://sonique.lycos.com/
